What else can I help you with?
When sunlight evaporates salt water does the salt stay behind?
Yes, salt remain as a solid residue.
How much salt can you remove by evaporation?
Evaporating the water will not remove any of the salt. Only the water molecules will evaporate. The salt will stay in the container.
Why does the ocean stay salty if fresh water is continuously being added?
Because water evaporates leaving the salt behind and re balancing the ratio between salt and water.
Is water more likely to evaporate with salt or with chemicals?
Water is water. It will evaporate no matter what is it. The real question is whether or not the chemicals or salt will evaporate with the water or not. The answer to that is no. The salt/chemicals will stay in the container.
Is dissolving salt in water a physical or chemical change?
Dissolving salt in water is a physical change- no chemical reaction took place. If the water evaporates, the salt is still there.
Can salt mack water stay cold?
No, salt water does not have any special ability to stay colder longer than regular water. The temperature retention of the water would depend on factors such as the initial temperature, the container it's stored in, and the surrounding environment.
How can you check if salt has dissolved?
If it is like salt and water you can just boil the water so water evaporates and salt stays at the edge :) or you can use simple destillation if you want the water to stay alone and salt to stay alone :) But the best thing you can do is to drink a little bit of it and see how it tastes :)
How is the sun used to disinfect water?
When the sun heats up water, the water evaporates. Since water is still light, the heavier, more solid materials stay in container that you are heating up. Therefore, if you put plastic above the container, it a) causes water to evaporate and purify itself faster, and b) collects the evaporating water.
What water evaporates quicker water or salt water?
Pure water evaporates faster. This is because the presence of impurities (salt) in the water causes the boiling point of the water to increase. The greater the difference between the boiling point of a substance and room temperature, the longer it takes for that substance to evaporate. So, pure water takes less time to evaporate. Of course, other conditions such as temperature, surface area to atmosphere, relative humidity and atmospheric pressure should be constant for both so as to investigate only the effect of salt on the evaporation of water.
How can you purify dirty water by just only the sun?
You can purify water using solar disinfection, also known as SODIS. Simply fill a clear plastic or glass container with dirty water, place it in direct sunlight for 6 hours (or 2 days if cloudy), and the UV radiation will kill harmful microorganisms. This method is effective for improving water quality in emergency situations or when other purification methods are not available.
How is salt made by evaporation?
Salt is not "made". Seawater is a solution of mainly water and salt. When exposed to sunlight, the seawater, because it's a liquid, evaporates and flyes away. However, salt, being a solid (even when dissolved), will not as easely fly away, and stay behind. It can then be collected and used.
How does salt water form freshwater rain in clouds?
Salt water evaporates from the ocean's surface, leaving behind the salt. The water vapor rises into the atmosphere and eventually condenses to form clouds. When the clouds cool and the water droplets become too heavy to stay aloft, they fall as precipitation, which is freshwater rain since the salt is left behind during the evaporation process.
